Explanation
Skull forms a protective covering for the brain . The main and overall function of the skull is to protect the brain and sensory organs and support facial structures.

Explanation
The brain , situated in the cranial cavity is an important internal organ. It is the control centre of our body. It controls the movements and all that we do. The brain is protected by the skull .

Explanation
The brain is the command center of the body, controlling everything from movement and sensation to thought and emotion. It processes information, sends signals to muscles and glands, and regulates various bodily functions, making it the central control system of the body.

Explanation
Science is the systematic study of the nature and behavior of the material and physical universe , based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms.

Explanation
The word ‘ Scientia ’ is derived from the Latin word Scientia which means ‘ knowledge ’. It is the field of human knowledge concerned with facts that are explained logically by rules, patterns, or principles.

Explanation
Hepatitis is a disease of the liver , not the respiratory system. Top Common diseases of the respiratory system include: Asthma Chronic obstructive pulmonary disease (COPD) Pneumonia Influenza (flu) Tuberculosis (TB) Bronchitis Emphysema Lung cancer Cystic fibrosis Pulmonary fibrosis

Explanation
Vitamin A (specifically, retinal) is necessary for the formation of rhodopsin, a light-sensitive pigment in the retina of the eye. Rhodopsin is responsible for black-and-white vision and is found in the rod cells of the retina. Vitamin A deficiency can lead to night blindness , a condition where people have difficulty seeing in low light environments.

Explanation
Isotopes of an element have the same number of protons .

Explanation
A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes

Explanation
Newton's first law of motion is also called as Law of inertia . Inertia is the ability  of a body by virtue of which it opposes a change. According to Newton’s first law of motion, an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The inertia of rest : When a body is in rest, it will remain at rest until we apply an external force to move it. This property is called inertia of rest. The inertia of motion:  When a body is in a uniform motion, it will remain in motion until we apply an external force to stop it. This property is called inertia of motion.
